Carbon monoxide gas is more dangerous than carbon dioxide gas. Why?
. With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.Carbon monoxide gas is more dangerous than carbon dioxide gas. Why?
Carbon dioxide (CO2) and carbon monoxide (CO) gases are emitted during the combustion of various fuels. Carbon monoxide is poisonous, whereas carbon-dioxide is non-toxic in nature.
Carbon monoxide is toxic because it is capable of forming a complex with haemoglobin (carboxy-haemoglobin), which is more stable than the oxygen-haemoglobin complex. The concentration range of 3-4% of carboxy-haemoglobin decreases the oxygen-carrying capacity of blood. This results in headaches, weak eyesight, nervousness, and cardiovascular disorders. A increased concentration may even lead to death.
Carbon dioxide is not poisonous. It proves harmful only at very high concentrations.
